The band-saw machine tool that workpiece movement saw frame is swung, the maximum difference with common band-saw machine tool are：In order to realize this hair
Bright workpiece movement and saw frame swing mode, and the overall structure and layout of band-saw machine tool make a big difference with existing product,
The workpiece travel mechanism and saw frame swing mechanism set up is that existing product is unexistent, specific as follows：
(1) task of cutting main motion and the feed motion of common band-saw machine tool undertakes by saw frame.The band saw of the present invention
Lathe, its saw frame only undertake the task of cutting main motion, do not undertake the task of feed motion.Feed motion task is held by workbench
Load.Therefore, the technology pattern of sawing is changed.Some advantages that arise therefrom is that workbench can increase rigidity, pass through screw mandrel
The structure design measure such as pair of nut and linear motion guide rail, the precision of table feed motion and the retentivity of precision are improved,
So as to ensure that the machining accuracy of sawing workpieces, reach " to saw for car ", the purpose of " to saw for milling ".Will particularly suitable for precision
Seek the Cutting indexes of high middle-size and small-size workpiece.
(2) the saw frame perpendicular cuts workpiece of common band-saw machine tool, in cutting process, saw band only cuts main motion and vertical
Feed motion, be on the one hand not easy chip breaking, the between cog of saw band is easily blocked in another aspect chip, is unfavorable for carrying for cutting-rate
It is high.Meanwhile saw band is easily generated heat, service life reduces.Therefore, the present invention is additionally arranged the weave mode of saw frame, makes saw band and work
There are three motion synthesis such as cutting main motion, vertical feed campaign and swing between part, the purpose is to make saw band in cutting process
In, micro-swinging is carried out, is advantageous to chip breaking and chip removal, so as to effectively improve cutting-rate, extends saw band service life.
New Sawing Process needs equipment and realized, therefore, the present invention devises the workbench of workpiece movement sawing
Feed arrangement and saw frame micro-swinging device.Meanwhile the technological process of numerical control saw cutting is developed, as shown in Figure 6.
Fig. 6 is the numerical control saw cutting process flow chart of the present invention.Main motion servomotor, feed motion servomotor and swing
Servomotor is each configured with controller and photoelectric speed detection means.After start, determined by parameter optimization controller optimal
Operation and control parameter.Main motion control loop, by photoelectric speed detection means and main motion servomotor, to band saw wheel
Speed be controlled, to ensure to run in the parameter area of optimization.Feed Motion Control loop, is detected by photoelectric speed
Device and feed motion servomotor, are controlled to the feed speed of workbench, to ensure to transport in the parameter area of optimization
OK.Oscillation controlling loop, by photoelectric speed detection means and wobble servo motor, the micro-swinging speed of saw frame is controlled
System, to ensure to run in the parameter area of optimization.
